Swing support is a mechanical part that supports two components to do relative rotational motion, which consists of six parts: outer ring (toothed or toothless), inner ring (toothed or toothless), rolling body (steel ball or roller), isolation block or cage, seal, nozzle, rotary support in various types of construction machinery, industrial machinery, cranes and other fields have a wide range of applications. Here are four types that are more commonly used. 1. Four-point contact ball swing support Four-point contact ball swing support, compact internal structure, steel ball and inner and outer ring arc roller into four points of contact, contact angle is usually 45 degrees, special also has 35 degrees or 55 degrees, four-point contact swing support can withstand axial force, radial force and overturning torque, double row than single row of all aspects of the tolerance is greater. 2. Single row cross-roller swing support Single row cross roller-type swing support, composed of two inner and outer ring, higher accuracy requirements, small assembly gap, roller for 90 degrees cross-arrangement, cross roller swing support can withstand greater axial force, radial force and tilt torque, due to larger load, higher precision, generally used in lifting equipment and military products. 3. Double-row heterosphere swing support Double volleyball swing support has three sets, one outer ring, two inner rings, or two outer rings, an inner ring composition, steel balls and isolation blocks can be directly discharged into the upper and lower raceways, according to the force conditions, the upper and lower rows of ditches loaded with different diameters of steel balls. Assembly of two halves with linked bolts into one, root this open swing support, assembly is very convenient, the upper and lower arc roller carrying angle is 90 degrees, can withstand a large axial force and tipping torque. Generally used in tower cranes with large capsized capacity, marine cranes and other heavy-duty machinery. 4. Three-row roller swing support Three rows of roller-type swing support has three seat rings, and double-row diameter ball, there is a ring has two halves, not the same is the three rows of rollers swing support three rollers up and down and radial rollers are separated, so that the load of each row of rollers can be determined, three rows of rollers can be selected according to the load of different diameter rollers, three rows of rollers swing support can be sustained at the same time. diameter. axis. Overwrite a variety of loads, is the four products of the largest carrying capacity of one, strong structure, especially suitable for heavy machinery with large loads, such as port cranes, steel and water operating platforms, shields and other heavy machinery and equipment.
